Description

The TWL1101 voice-band audio processor (VBAP) is designed to perform the transmit encoding analog/digital (A/D) conversion and receive decoding digital/analog (D/A) conversion, together with transmit and receive filtering for voice-band communications systems.The device operates in either the 13-bit linear or 8-bit companded m-law mode, which is selectable through the
I²C interface.From a 2.048-MHz master clock input, the VBAP generates its own internal clocks.The TWL1101 device is characterized for operation from 40°C to 85°C.
